Project Description

For the interconnection of a 1.5MW Solar installation, the utility not only needed the usual upgrades for the interconnection, but also the development of a new 3V0 detection protection scheme.

Outcome

As the lead engineering consultant supporting the interconnection of a 1.5MW Solar installation on to the utility’s system, PRE provided detailed engineering design for the substation upgrades required for the interconnection and developed a 3V0 protection scheme standard for the utility to prevent a back-feed of the line in the case of a fault.
